TCC’s Bottom Line

The 2018 Audi S6 stands with an impressive hand: quality interior, great performance, functional shape. It's possible to find better examples from other cars, but they all cost significantly more.

The 2018 Lexus GS is a worthy rival to its German foes in terms of luxury and handling, but its engine lineup is falling behind the competition.

The 2018 Mercedes-Benz E-Class goes to excess--the right kinds of excess--to preserve its best-of status.

TCC Likes

Underrated V-8
Well-appointed interior
Sharp 7-speed dual-clutch automatic

Comfortable, supportive front seats

Elegant sedans and wagons, pretty two-doors

TCC Dislikes

Overshadowed by S7
Steering is too light, too quick?
Exterior is too conservative

F Sport's stiffer ride
Responsiveness in GS 300
Mediocre mileage for GS 350

COMAND infotainment is kludgy
Slim trunk space on two-doors
Powertrain noise more prominent
